Name: ___________________________________________________ Date: ______________ 4. You flip a coin twice. a) Complete the tree diagram to show the sample space. First flip Second flip Outcomes b) What is P(H, H)? P( , ) c) Check your answer using multiplication. P(H, H) = P( ) × P( ) = 5. Grade 8 students are planting 4 types of flowers: daisy (D), marigold (M), rose (R), and tulip (T). The students can plant them in 4 places: school (S), flowerpot (F), park (P), and hospital (H). Tamira does an experiment to see where the different flowers will be planted. The sample space is (M, F), (R, H), (D, S), (M, F), (T, H), (T, P), (D, H), (R, P), (M, P), (R, F). a) What is the experimental probability of getting P(marigold, flowerpot)? P(M, F) = ← number of favourable outcomes 10 ← number of trials b) Use multiplication to find the theoretical probability of P(marigold, flowerpot). P(marigold) = P(flowerpot) = P(marigold, flowerpot) = P(marigold) × P(flowerpot) 620 MHR ● Chapter 11: Probability
